This is Tanusree Chatterjee from Kolkata, West Bengal, India seeking for help on few basic concepts of routing protocols and its applications in Content Centric Network. Can you please clear my confusions about, in Link State Protocol, when there is an update/change in the routing information of any router, whether it is propagated to the direct neighbors only or broadcasted to the entire network? And what will be the advantages or disadvantages of using Distance Vector Routing in Content Centric Networks?
